Running Developers preview & BitLocker encryption, need a software rollback before updating to Lumia Cyan

wp8.1 12393Over at conversations, Microsoft mobile has mentioned in an article that,

If you are registered to Windows Phone Developer Preview Program, you might need to use the Nokia Software Recovery Tool to return your Lumia to a normal commercial software before downloading the Lumia Cyan update.

Now, we understand here that ordinary customer Lumia devices with Windows Phone 8.1 developer preview will get “Lumia Cyan” firmware normally and we have information about many Lumia 625 and Lumia 925 with WP8.1 dev preview getting Lumia Cyan firmware OTA.

Issue is with corporate Lumia users with BitLocker encryption. Those enterprise customers which have BitLocker encryption enabled may need to use Nokia Software Recovery Tool to return to the latest software + firmware version, before updating to Lumia Cyan.

    • Kamal

      What exactly is ur problem??

  • Please help me. I rolled back my 925 to wp8 and then to lumia cyan (through nokia recovery tool). I had no idea that bitlocker encryption would enable if i connected to microsoft exchange. I spend a weeks time finding out that my memory is not recogonised by my laptop. Then i heard about Bitlocker issue with lumia cyan. Now, is it impossible to have a decrypted memory while running lumia cyan with bitlocker enabled ?

    how can i downgrade my lumia 530 from windows 8.1 to 8.0?

  • Jussi

    I`ll suspect the sudden freezing with no reason on my L930 is caused by bitlocker. Phone starts to generate heat by itself gets massive lag on all (like in the old days on PC when processor was at 100%).
    And yes I have bitlocker, exchange account, corporate policy loaded on it…

      Update worked OTA.

        But found cyan available for middle east versions also…
        Now don’t know wat to do…

        I do not believe that you updated your Lumia 925 dev preview to Cyan in Poland.
        Most probably you have different FW version – not Poland generic.
